Bulletin

Solar activity was low, with an isolated C2.8 flare produced by spotless region NOAA 2627 near the west limb on 28 January at 21:09UT. A new active region rotated over the east limb with only a few tiny spots. NOAA 2628 and NOAA 2629 were quiet. No earth-directed coronal mass ejections (CMEs) were observed in available coronagraphic imagery. The greater than 10MeV proton flux was at nominal levels.

Mostly quiet flaring conditions are expected, with a small chance on a C-class event.

Solar wind speed declined from 540 km/s to values around 460 km/s under the waning influence of the coronal hole's high speed stream (HSS). Bz fluctuated between -4 and +4 nT. The interplanetary magnetic field was mostly directed away from the Sun. A negative CH is transiting the central meridian (CM) and may start influencing the earth environment around 31 January, probably preceded by a sector boundary crossing (SBC).

The geomagnetic field was at quiet (Dourbes) to unsettled (Kp) levels. Mostly quiet to unsettled conditions are expected till the arrival of the SBC and the CIR/HSS structure from the negative CH, when active episodes may become possible.

Today's estimated international sunspot number (ISN): 033, based on 09 stations.
